Just eight countries are expected to be behind 50% of the population growth over the next 30 years. Five are in Africa.
In its analysis of this milestone, the UN makes two key observations. The first is that the global population has been expanding at its slowest rate since 1950. The growth rate dropped below 1% in 2020, a trend that is likely to continue.
Appreciating these numbers requires an understanding of the distribution and demographic structure of the population. Where are these people across regions, countries, and rural and urban geographies?. Population growth can be a blessing, spurring economic growth from shifts in a population’s age structure. This is a prospect if working-age people have good health, quality education, decent employment and a lower proportion of young dependants.
The consequences of population growth are socioeconomic, political and environmental. Some of them can be negative. How these unfold is determined by the characteristics of the population and its distribution.The major factors driving population growth in these countries include low contraceptive use, high adolescent fertility rates and a prevalence of polygamous marriages.
